Mitsubishi Lancer hesitates after slowing down
 

My 2011 Lancer ES has a problem where if I do not come to a complete stop and then press on the gas, it tends to take a half to full second before it kicks in, and I am not sure of what the fix is. I've changed spark plugs and cleaned fuel injectors and replaced air filter and tried to clean the throttle body, but the problem is still there. Now I am thinking about a new pedal acceleration sensor, but it works fine when I am at higher speeds and the problem is only there if I slow down at a low speed(such as a yield) before stepping on the gas. Any Ideas?
